Hedging plants in Ireland (size, spacing, flowers and fruit)

Common question that new gardeners often ask.......

How far apart to space hedging plants?
Which hedge will grow by the sea?
Which hedge will cope with shade?
Which hedge flowers in winter?
Which hedge has flowers and fruit?
What variety makes a good security hedge?


You will find answers to your hedging questions here, within this basic list of some of the most suitable hedging for Ireland.
I will update it as time goes by, with pics of the individual hedging plants, plus many more suitable varieties.

When selecting a hedge for your situation, you will be choosing a variety which balaces the following factors....
* How high you require your hedge to grow
eg. Is it to be 1.5 metres high as a boundry between houses.

* How quickly you wish your hedge to get to that required height
eg. immature Box hedging will probably not reach 1.5 metres in your lifetime whereas X Cupressuscyparis 'Leylandii' will reach that height in just over two years, but continue growing strongly.

* Level of maintenance required
How much maintenance (trimming, topping etc.) is required to keep your hedge within the desired heights and widths you require
eg. To keep a Griselinia littoralis hedge at a height of 1.5 metres will require trimming once if not twice a year. Whereas trying to keep X Cupressuscyparis 'Leylandii' to a height of 1.5 metres is the devils own job, with the hedge growing very strongly and not responding well to hard pruning.



So as you can see, it is worth your while to carry out some research and reading into hedging before selecting your variety. If not, that fast growing hedge could become the bane of your life with its constant maintenance.
Finally, do not be put off by the ultimate heights quoted for some hedging varieties eg Griselinia littoralis at 20 metres tall, these are maximum heights, under ideal conditions, unpruned and with no neighboring plant competition.
If we disregarded hedging based solely on their ultimate heights, then we, as gardeners, would never plant Beech as a hedge, as it has an ultimate height of 35 to 40 metres.
Never planting beech (Fagus sylvatica) would be a shame.

Read on and discover which plant may be suitable for your next hedge........

[medieval knievel]

that's an impressively comprehensive list.

i've planted a beech hedge at between 12"-18" between plants, and have interplanted with holly seedlings i got from a friend. the plan is to let the beech grow, but as the holly plays catchup, slowly prune in such a way that it either intermingles with the beech or completely replaces it. is that a sane way of going about it?

the hedge will ideally end up about three to four foor tall.

That's a fantastic amount of information GPI.... laid out so clearly too....I wish I'd had it a couple of years ago when I was choosing my hedges!

excellent stuff
